HARTFORD— A South Windsor man previously sentenced to eight years in prison for stealing a .50-caliber Bushmaster rifle from an East Windsor gun shop pleaded guilty in federal court on Tuesday to stealing a different firearm from the shop days earlier.

Jordan Marsh, 27, pleaded guilty before U.S. District Judge Michael P. Shea in Hartford to stealing a Windham Weaponry 5.56 caliber semi-automatic rifle from the front counter of Riverview Gun Sales on Dec. 11, 2012, according to a press release from the U.S. Attorney's office.

Marsh was captured on the store's video surveillance system stealing the Windham, but no employees saw the theft or even realized the gun was missing until Hartford police found it in Marsh's hotel room on Dec. 17. Marsh had been arrested on Dec. 15 for trying to steal the Bushmaster rifle, the release states.

Earlier in 2012, Marsh was convicted on state felony charges for stealing approximately 12 other guns from Riverview, the release states.

Marsh faces a maximum sentence of 10 years in prison when he returns to court on Dec. 17.

Riverview's federal firearms license was revoked by the Bureau of Alcohol, Tobacco, Firearms and Explosives in December 2012, and its owner, David Laguerica pleaded guilty in August to violating federal firearms laws. The ATF revoked the license shortly after Laguerica handed over records showing the shop had sold a handgun and a Bushmaster AR-15 semi-automatic rifle to Nancy Lanza, mother of the gunman in the Dec. 14 massacre at Sandy Hook Elementary School in Newtown.
